Initially i didn't understand well what you said. So for your problem i think
that's more relevant what Daniel and Tony hava told you. Cluster VIPs that you can add with Oracle clusterware from 10gR2 is a method to
use Oracle Clusterware as an HA software, this document http://www.oracle.com/technology/products/database/clustering/pdf/twp_oracleclusterware3rdparty%5B1%5D.pdf explains well the concept.
Maybe, but this is only a bad trick, you can add VIPs for your isolatet batch subnet on
every node and then add other listeners, but as Oracle Suppord has already told you
this i not supported by Oracle.
